GL4Java MAC Installation ! If the AppleScript Installation failes, you can copy the files manually. The folder "sysextensions" represents the destination folder of your MACOS, which is usally located under MACOS:system:extensions !! Just copy the contents of "sysextensions" to the recursively ! Thats all ! Prerequisites: MRJ Java Runtime OpenGL Sources: http://www.jausoft.com/gl4java/ Notes: The stencil buffer and the accum buffer DOES work, but e.g. the hardware accelerated ATI OpenGL Renderer does NOT :-( But GL4Java does select the hardware renderer first, if avaiable ! So, you have to disable the hardware renderer, if you want to use those features (if the hardware renderer is "broken") ! Use the "extension on/off" tool to achive this action ! To check the installation, just start the GL4JavaInfo-Script ! You should also download all the demos ... Yours, Sven Goethel
